31. Connect the output shaft (countershaft) speed

sensor connector.

32. Clear the DTC with the HDS.

33. Start the engine, disable the VSA by pressing the

VSA OFF button, run the vehicle in D, and hold the
vehicle at speeds over 12 mph (20 km/h) for at least
10 seconds when the transmission is not shifting.
Slow down and stop the wheels.

34. Monitor the OBD STATUS for P0721 or P0722 in the

35. Replace the output shaft (countershaft) speed

sensor (see page 14-205).

36. Reconnect all connectors.

37. Turn the ignition switch to ON (II).

38. Clear the DTC with the HDS.

39. Raise the vehicle on a lift, make sure it is supported

securely (see page 1-10), and allow all four wheels
to rotate freely.

40. Start the engine, disable the VSA by pressing the

VSA OFF button, run the vehicle in D, and hold the
vehicle at speeds over 12 mph (20 km/h) for at least
10 seconds when the transmission is not shifting,
then slow down and stop the wheels.

41. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals at the output shaft (countershaft) speed
sensor and the PCM, then go to step 1.

Go to step 42.

42. Monitor the OBD STATUS for P0721 or P0722 in the

DTCs MENU with the HDS.

Troubleshooting is complete. If any other

Temporary DTC or DTCs were indicated on step 41,
go to the indicated DTCs troubleshooting.

If the screen indicates FAILED, check for poor

connections or loose terminals at the output shaft
(countershaft) speed sensor and the PCM, then go
to step 1. If the screen indicates NOT COMPLETED,
go to step 40.

43. Update the PCM if it does not have the latest

software (see page 14-8), or substitute a known-
good PCM (see page 14-9).

44. Raise the vehicle on a lift, make sure it is supported

securely (see page 1-10), and allow all four wheels
to rotate freely.

45. Start the engine, disable the VSA by pressing the

VSA OFF button, run the vehicle in D, and hold the
vehicle at speeds over 12 mph (20 km/h) for at least
10 seconds when the transmission is not shifting,
then slow down and stop the wheels.

46. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals at the output shaft (countershaft) speed
sensor and the PCM. If the PCM was updated,
substitute a known-good PCM (see page 14-9), then
go to step 45. If the PCM was substituted, go to step
1.

Go to step 47.

47. Monitor the OBD STATUS for P0721 or P0722 in the

DTCs MENU with the HDS.

If the PCM was updated, troubleshooting is

complete. If the PCM was substituted, replace the
original PCM (see page 11-205). If any other
Temporary DTCs or DTCs were indicated on step
46, go to the indicated DTCs troubleshooting.

If the screen indicates FAILED, check for poor

connections or loose terminals at the output shaft
(countershaft) speed sensor and the PCM. If the
PCM was updated, substitute a known-good PCM
(see page 14-9), then go to step 45. If the PCM was
substituted, go to step 1. If the screen indicates
NOT COMPLETED, go to step 45.

Speed Sensor Intermittent Failure

NOTE:

• Before you troubleshoot, record all freeze data and

any on-board snapshot, and review General
Troubleshooting Information (see page 14-4).

• This code is caused by an electrical circuit problem

and cannot be caused by a mechanical problem in the
transmission.

1. Record all freeze data, and clear the DTC with the

HDS.

2. Test-drive the vehicle for several minutes in D

through all five gears under the same conditions as
those indicated by the freeze data. Slow down and
stop the wheels.

3. Turn the ignition switch to LOCK (0), and repeat the

test-drive in step 2.

4. Monitor the OBD STATUS for P0723 in the DTCs

MENU with the HDS.

Intermittent failure, the system is OK at this

time. Check for poor connections and loose
terminals at the output shaft (countershaft) speed
sensor and the PCM.

If the screen indicates FAILED, go to step 5. If

the screen indicates NOT COMPLETED, return to
step 2 and recheck.

5. Turn the ignition switch to LOCK (0).

6. Disconnect the output shaft (countershaft) speed

sensor connector, and inspect the connector and
the connector terminals to be sure they are making
good contact.

Go to step 7.

Repair the connector terminals, then go to

step 7.

7. Connect the output shaft (countershaft) speed

sensor connector.

8. Test-drive the vehicle for several minutes in D

through all five gears under the same conditions as
those indicated by the freeze data. Slow down and
stop the wheels.

9. Turn the ignition switch to LOCK (0), and repeat the

test-drive in step 8.

10. Monitor the OBD STATUS for P0723 in the DTCs

MENU with the HDS.

The problem has been corrected.

If the screen indicates FAILED, go to step 11. If

the screen indicates NOT COMPLETE, return to step
8 and recheck.

11. Turn the ignition switch to LOCK (0).

12. Jump the SCS line with the HDS.

13. Disconnect PCM connector B (44P).

14. Disconnect the output shaft (countershaft) speed

sensor connector.

15. Check for continuity between output shaft

(countershaft) speed sensor connector terminal
No. 2 and body ground.

Repair a short to ground in the wire between

PCM connector terminal B40 and the output shaft
(countershaft) speed sensor connector, then go to
step 24.

Go to step 16.
